Device for measuring the ring size of a finger

ABSTRACT

A device for measuring the size of a finger to determine the size of the ring that will fit the same. A disc is journaled in a casing formed of two parts. The disc carries a chain that is anchored on the exterior of the casing and on the disc within the casing so that the chain when pulled out of the casing is in the form of a loop through which a finger to be measured can be inserted. An arm carried on the disc has a pointed end exteriorly of the casing so that the size ring that will fit the finger is readily determined. When the chain links are not used for measuring they will readily retract into the casing by turning the disc.

firm} Gardner DEVICE FOR MEASURING THE RING SIZE OF A FINGER Thisinvention relates to a ring finger measuring device to determine thering size of a ring therefor.

It is an object of the present invention to provide a finger ringmeasuring device for measuring upon the finger a size of a ring that canbe applied thereto in which there is eliminated the need for usingseveral ring size devices to determine the ring size of the finger.

It is another object of the invention to provide a measuring device fora ring finger incorporating a wrap around element such as a chain onwhich the actual measurement of the ring or chain extended from thedevice can be determined and translated by the mechanism within thedevice; and wherein the ring size is determined from an indicating scaleon the face of the device with an indicating arm extendable over thescale.

It is another object of the invention to provide a ring finger measuringdevice wherein the chain parts when not engaged around the finger, canbe retracted into the device and protected while the device is beingcarried in the pocket of a jeweler.

Other objects of the invention are to provide a ring finger measuringdevice of the type described, which is of simple construction, has aminimum number of parts, light in weight, efficient and effective inuse.

For a better understanding of the invention, reference is made to thefollowing detailed description taken in connection with the accompanyingdrawings, in which:

FIG. 10 is an enlarged top view similar to FIG. 7, showing the chainextended to form a finger loop, and the indicator arm located at thescale.

FIG. 11 and FIG. 12 enlarged are cross-sectional views taken on linesll1l and 12-l2 respectively.

Referring first to FIGS. 1-6, the ring measuring device 10 includes ameasuring chain 11 extended from the device and applied to a finger F onwhich it is desired'to fit a ring. This measuring device 10 furthercomprises a casing having a bottom part 12 in which there is mounted forrotation a disc 13 to which the chain 11 is attached at one end. A topcasing part 14 is secured to the bottom part by fastening screws 15extending through holes in cylindrical walls or flanges 16 and 17 of therespective bottom and top parts 12 and 14. The disc 13 protrudes throughhole 35 in annular bottom wall 12a of casing part 12, and is restedthereon by annular flange 18. The measuring chain 11 is anchored at oneend to the flange by lug 19; see FIG. 4.

The upper part of the disc protrudes through hole 37 in the top wall 14aof easing part 14, and has a transverse or diagonally extending guideslot 21 for an upstanding knob or button 22 attached to a radiallyextending indicator arm 23 slidable in a radially extending slot orpassage 24 located externally on the top of the upper casing wall 14a.This arm 23 has an opening 26 through which numerals 27circumferentially inscribed on the top surface of the upper casing wall14a can be viewed to determine the measured ring size and the size ofthe ring which will fit the finger F. On the outer periphery of the topcasing wall 14a over which the arm 23 will rotate is a series ofserrations or notches 28 with which a downwardly and inwardly bentpointed end 29 will register. The pointer engages in the serrations 28and is retained in position as shown in FIG. 5 after the chain 11 andthe measuring device 10 are slipped from finger F.

The tapered end 29 of the arm 23 is maintained in registry with theserrations 28 by a tension spring 31 connected at its inner end andanchored at its outer end in recess 32 in the disc.

The top casing part 14 may be split at line 33, FIG. 5, to facilitatethe assembly of the casing part 14 into the bottom part 12. The chain 11passes through an opening 34 in flanges l6, l7 and is anchored at itsouter end to lug 36 at the exterior of the casing part 12, whilepermitting the chain to be adjusted in and out of the casing. The linkscan be pulled inwardly as shown in FIGS. 2, 3 and 4 by manipulating thearm 23 and the disc 13 to wind up the chain on the disc flange 18 asbest shown in FIG. 4.

By pushing outwardly on the knob or button 22, the other end 29 of thearm 23 can be released from the serrations 28 and the round knob canthen be turned with the thumb and finger to turn the disc and retractthe chain through opening 34 in casing parts 12 and 14.

In use the chain can be similarly extended by unwinding the same fromthe flange 18 of the disc 13 and pulling out the chain to provide anadequate opening in the exterior chain P to accommodate the finger F.The chain will be again wound up and tightened on the finger by turningknob 22 so an indication can be given by the arm 23 of the size number27 as these numbers appear in the window 26 of the arm 23. Thereafterthe chain is slipped from the finger; however, the arm 23 is retained inplace by the action of the spring 31 pulling inwardly upon the arm 23and the engagement of pointed end 29 in serrations 28. Once the ringsize is determined, the links exterior of the measuring device can bepresented over a finger ring to determine the size of the ring that willfit the finger. In this manner the ring size can be determined if thering is not marked with the size. Otherwise, a ring of known or markedsize corresponding to the size indicated in window 26 can be selected.

FIGS. 7-12 show another finger measuring device 10A which is generallysimilar to device 10 and corresponding parts are identically numbered.In device 10A the top casing part 14 is flat annular flange which fitsin bottom part 12. A pair of radially extending lugs 40 are formed atthe periphery of this flange and engage in notches 42 formed in the topof cylindrical casing wall 16a. A screw 44 extends through a hole 45 inflange 14 and is seated in threaded hole 46 formed in a lug 48 on theinside of easing wall 16a; see FIG. 12.

Chain 11 extends outwardly of hole 340 in casing wall 16a. The outer endof the chain is secured to lug 360 on the outside of wall 16a. Theinside end of the chain is engaged on flange 18a of disc 13a. Scalelines 49 are inscribed on flange 14' with numbers 27a located at outerends of the lines; see FIG. 10. A series of notches or serrations 280are formed along the rim of hole 37a of flange l4. Pointed tip 29a ofarm 23a engages in these serrations. The arm is slidably disposed in aradial slot or passage 24a formed in a channel 50 which extends upwardlyabove the disc; see FIGS. ll, 12. The arm is urged radially outward by acompressed spring 31a in channel 50. Knob or button 22 is movable alongguide slot 21a which communicates with passage 24a.

Chain 11 is extended outwardly to form a loop by turning disc 13a. Thisis done by turning knob 22. A pin 52 is further provided on top of thedisc extending outwardly to assist in turning the disc if necessary.Spring 31a operates in a radial direction opposite to that of spring 31ain device 10 to urge the arm outwardly to the rim of hole 370. The arm23a engaged at one of the serrations 28a indicates the ring at one ofthe scale lines and numerals. In both devices 10 and 10A whole integersare marked on the top late of the device. These numerals are inscribedat alternate lines. Thus lines between numerals indicate half sizes.

After use the disc is turned to retract the chain. The device can thenbe placed in a jewelers pocket where it will occupy very little space.

Both devices and 10A make it unnecessary for a jeweler to providehimself with a large number of dummy rings, or other finger measuringdevices. Just one measuring device as described herein will measure allfinger sizes.

The parts of the devices described herein can be made of lightweightmetal, metal or plastic. The devices can be made up in overall sizes nolarger than a pocket watch or even smaller, so that they can beconveniently carried in a garment pocket.
